Collaborate Disseminate
Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of …read more Continue reading The Inner Machinations of the Arduino are an Enigma
We often take our “SoftwareSerial” libraries for granted, and don’t investigate what goes on under the hood — until they fail us, at least. Would you like to learn how …read more Continue reading Animate Arcane Protocols With Interrupt-Backed Bitbanging
Do you ever have to ensure that an exact amount of time passes between two tasks in your microcontroller code? Do you know what’s the difference between precision and accuracy? …read more Continue reading Time And Accuracy in Las ATMegas
The planned threading in shared memory update gives bad actors a way around the timer mitigations released by browser vendors. Continue reading WebAssembly Changes Could Ruin Meltdown and Spectre Browser Patches
[Fatjedi007] recently acquired three programmable boxing gym-type clocks to help his developmentally disabled clients manage their time. The plan was to have timers of varying lengths fire at preset times throughout the day, with the large displays providing a view from anywhere. Unfortunately, the clocks were not nearly as programmable as he needed them to be.
Since he’d spent enough money already, [Fatjedi007] turned to the power of Raspberry Pi to devise an affordable solution. Each clock gets a Pi Zero W and a simple IR transmit/receive circuit that operates using LIRC. The clocks came with remote controls, so it …read more
